Ninja turtles art

Looking back now, it seems strange that, as children, we readily accepted the concept of four crime-fighting turtles with a love for pizza and a rat for a mentor.

But the damage is already done, and we still give rats an easier ride than they deserve, in the hope that one might teach us the art of ninjitsu.

We're clearly not alone. Other slightly disturbed Teenage Mutant Ninja Turtles survivors have assembled in Philadelphia for an entire art show based around Leonardo, Raphael, Michelangelo and Donatello.
